YORK PROSPERITY COMPANY, INC., OF SYRACUSE, NEW YORK, A CORPORATION OF-AUTOMATIC TRAY rREss Application filed May 16, 1924, Serial No. 713,699.Renewed December 12, 1929.

This invention relates to combination conveyor pressing machinery andmore particularly to automatic tray presses and one 'of the mainpurposes is to improve the tray pressing machine disclosed in my jointapplication for- Patent Serial Number 708,756 filed April 19,

1924, to the end that the entire machine be power driven and automaticin operation.

A further object is to produce improvements in respect to pressingmachinery and garment handling means whereby the work is more rapidlyplaced Within the press and removed therefrom; and to this end myinvention is so constituted that the press operator stands from thevicinity of the press jaws rendering personal accidents impossible. Thegarment is s read out upon a flat conveyor or tray sur ace wherevisibility of the work on the tray is exceptionally good and theoperator is not hampered 'by' having to spread the garment across andinto the hot press jaws; and since he does not work inside the pressaws, the press head is not required to open so high .above the buckwhich aflords simple construction and requires less power to open andclose the press than in wide opening long stroke pressing jaws.

' Furthermore, my improvements increase the working efliciency ofpressing machines as regards the production, in that the quantity ofwork turned out is somewhat increased because the operator does not losetime be tween pressing periods for while one garment or set of garmentsis being treated in the press or heating zone, the operator is engagedin removing the pressed garments from the trays and spreading outunpressed garments on the conveyor and making ready for the nextpressing operation and period. For the purpose of illustrating theinvention. the accompanying drawings show a twopart or multi-unitgarment or work conveyor, but other forms, or even a single conveyor,may be'incorporated into the pressing machine; and a feature of theinvention is the roll in and roll out double tray or work carrier whichcrosses one over the other in approaching and leaving the press.- Theconveyor improvements constitute a large saving in floor spacefor thereason that, regardless of the size of .the conveyor tray, apron orother means for holding the garment, the

pressing jaw members which was due to the fact that as one tray orconveyor unit moved into the press from one side, the other tray bearingthe finished goods was ejected from the press on theother side; andtherefore the actual floor space required for anordinary conveyor presswas usually about three times i the area of one of the press jaws.

I employ a' back and forth conveyor, the units of'whichv pass each othergoing in op posite directions, and which are moved in and out of thepress from one side of the machine only. While my conveyor cars or traysare illustrated as traveling on tracks, my invention is not limited tosuch construction. I

' The drawings Figure 1 illustrates a side view of my impress andautomatic tray conveyors, the pressing jaws being closed down upon thework with'one tray in the press and the other tray outside thereof inunloading and reloading position; and Figure 2 illustrates a plan viewthereof with the garment press head removed to expose the one tray inpressm' g 1 position above the buck. 7

Figures 3 to 6 inclusive illustrate a series of side views of the trayconveyors in their several different positions forthe purpose of moreclearly disclosing the traveling movement of said trays; and furthermerethese views portray the mode of operation characteristic of the trayconveyor-haulin means which consists of an automatic catc and releasedevice whereby the'carriage runs forwardly free of all trays carrying notrays at all in its forward stroke away from t e 80 proved combinationpower driven garment press jaws, but the carriage picks up a tray at theouter end of its travel and then stands ready to haul in the traybearing the new work when the press aws start to close. In this respectmy improvements are so laid out that during the opening stroke of thepress jaws the conveyor remains at rest but when the aws start to closethe trays likewise start movement and then we have an automaticsimultaneous jaw closing and conveyor traveling function which is afeature of my invention. However, it is to be appreciated that theopening cycle of the jaws may as well be synchronized with the traymovement, but in the present description I have chosen the press closingcycle as the one by which the tray movement is associated.

Figure 3 shows the two trays in their limited position of travel,namely, one tray being in pressing position and the other being outsideof the press to deliver'old work and receive new work. Figure 4 showsthe trays crossing one over the other. Figure 5 illustrates thecompletion of the overhead crossing movement whereby the right hand trayof Figure 3 travel and has exchanged positions as compared to theposition of the trays in Figure 3. Figure 6 shows the trays in the sameposition as in Figure 5, but a traveling carriage member is in the actof starting forwardly to pick up the outer tray for the purpose ofmoving it inwardly with its work to the pressing jaws.

Figure 7 shows a plan view of one set of rails in the track system whichpermits the roll in and out movement of the trays whereby one is causedto cross over the other.

Figures 8 and 9 illustrate cross sectional views taken on the lines 8-8and 99 respectively of Figure 7.

Figure 10 shows a diagram of the trays connected by a flexible cablewhereby the movement of one conveyor tray is transmitted to the othertray; and Figure 11 shows a similar diagram with the exception that Elietrays are in reversed or exchanged posi- A description will first begiven of a suitable form of pressing machine for the purpose of morecomprehensively explaining my improvements in respect to power operatedtray conveyors; and thereafter the conveyor system will be described andset into the press.

The pressing machine A pressing machine frame in Figure 1 consists oflegs 15 which support a bed or press buck 16 over which is disposed apressing head 17 which raises and lowers in relation to the buck or bed16 for pressing the work disposed therebetween and it is undertsood thatsaid work is conveyed to and from the press bed, into the press jaws, bythe tray has completed its outward conveyors hereinafter described indetail. The numeral 12 designates the meeting jaw or pressing surfacesand is the pressing plane. A press lever 18 is pivotally mounted on ashaft 19 carried in the frame 15 and the outer lower end of the lever 18projects downwardly where it pivotally connects with a connecting rod 20which is reciprocated by a crank or driving wheel 21 anchored to a powerdriven shaft 22 carried in a'gear housing 23. The connecting rod 20 hasits outer end pivoted at 24 on the lower end of the press lever or yoke18 while the front end thereof is mounted on a pin 25 forming part ofthe power driven crank or driving Wheel 21. A motor 26 has a main driveshaft 27 journaled in the gear housing 23 and acts to rotate the powershaft 22 for the purpose of reciprocating the connecting rod 20 in orderto rock the press lever 18 back and forth on. the shaft 19 for thepurpose of raising and lowering the head. It is to be understood thatany suitable motive power means may be employed for reciprocating theconnecting rod 20 and in this connection the crank or drive wheel 21 maybe directly connected to the press lever 18 or assume other relationswith the press lever so long as a rocking motion is imparted to thepress lever.

A continuously running or stop and start motor may be employed forcausing the head to dwell on the buck to prolong the pressing operation.In the present case the former type motor means is employed and soclutching mechanism may be used for stopping and starting the drivingwheel or crank 21. It is understood how any well known type clutch maybe employed for driving the connecting rod 20 to outward pressingposition as in Figure 1 and then produce a half revolution of the crankdriver 21 to pull up the head. A control handle 28 is placed at thefront of the machine in convenient reach of the operator to stop andstart the motor 26 or the crank driver 21 and is designed to oscillate ashaft 29 through a universal joint if needed. A pendulum bob 14 isanchored to the shaft 29 and swings freely againstand cooperates with aclutch lever 13 for appropriately controlling the motor or power shaft22 whereby the shaft is caused to make a one-half revolution to open thepress and another half revolution to close the press. The lower end ofthe clutch lever extends into the gear housing to control the clutchingmechanism but since I do not claim the clutch it is not shown in detail.

The above described pressing machine preferably embodies a relativelypressing head 17 for it will be understood how pressing jaws arerequired to open a short distance only inasmuch as the work is notspread upon the buck 16 but is spread upon one of the trays andthereafter travels into the press. Extended visibility of the shortstroke has an unobstructed view of the tray upon which he spreads thegarment. In this I have weight, it is desirable to counterbalance it ina lifting force against the head 17 whereby made a distinct improvementand advance in the art for with the advent of Wide opening modern typegarment presses the producer has concerned himself with the developmentof means for lifting the head high above the buck which sometimesrequires complicated structure all of which my invention eliminates.

Since the press head 17 is of substantial such away that it readilymoves up and down .without strain 'on the motor driving mechanism; andto this end the frame 15 has arearward projection on which a bell crankarm 10 is fulcrumed at 5. Thelong ,arm'lO of the bell crank is providedwith a counterbalance weight 9. The upstanding short end 8 of the bellcrank carries a pin 7 which floats in a slot 6 made in the lower arm 18of the press lever. The substantially heavy weight 9 therefore actsthrough the rather long lever arm 10 against the press lever 18 toexercise the said head'and the said counterbalance -weight are made toapproximately balance one with the other to permit a smoothly operatingmechanism-and to avoid over-working the motor 26 during the head liftingmotion.

The canveyo'r In the first place the conveyor occupies little spacebecause of its overhead crossing function and is automatic in operation.A rectangular tray frame 30 is usually constructed a little larger-thanthe pressing jaws of the machine withwhich the trays are to be used, anda canvas stretcher 31 is held tautly in the frame 30 by lacings 32 andthe stretched canvas work carrier 31 conveys the garments to the pressjaws. For convenience in description, one of the trays is denoted by 30while the other tray is pointed outby the numeral 29. The tray 30 may attimes also'be referred to as the upper tray and the tray 29 as the lowerone, though no such distinction in fact exists for-a novel feature isthe means whereby both trays come to rest in the same plane when insidethe jaws. However, the tray 30 travels above L the tray 29 in its backand forth travel. In

Figure 2 the press buck 16- is shown disposed underneath the lower tray29 which illustrates how one garment tray is left in-press- 29 undergoesa straight back and forth movement in and out of the press jaws alongthe track 37 and comes to rest inside the press with its canvasstretcher coincident with the pressing plane 12. The tray 30 is fittedwith front rollers 38 which are adapted to roll on the track rails 39while the rear edge of the tra 30 is equipped with outside wheels or rolers 40 adapted to travel upon the outer track section 41.

My improvements constitute means for crossing one conveyor tray over theother as already suggested during the in and out or back and forthtravel to and from the press, and one means to this end resides in thenovel track structure illustrated but other facilities may be employedto accomplish this result without departing from the principle extendingfrom the rear edge ofthe press jaws to the front end of the conveyorframe 11 support which holds the track in proper position. This permitsthe-tray 29 to run the full length of the simple track 37 and passunderneath the tray 30. On the other hand. the outer track 3941 is madein two sections, as denoted by the numerals 39 and 41, and the rear traywheel shaft 35 reaches across the track rails 37 and 39 in order to findsupport on the outer upper track section 41. The forward end of thetrack 37 may be bent down at an angle to the horizontal as well as thefront track sections39 for the purpose of bringing the tray to outwardrest where it is held inconvenient angulaig position' for the loadingthereof. The inner track system alongside the pressing jaws ishorizontally disposed and so constructed as to cause the conveyorstretcher supports 31' remove into the pressing plane 12. and" this ischaracteristic of both track systems. The upper and lower guide trackmeans or track SYSiEIXI 37.. 39 and 41 aflords guide means on which thetfiwo work carriers 29 and 30 pass each other in back and forthmovementsto and from the press jaws. 1 i

It is to be noted that one of the trays, in this instance 30, has itsrollers or wheels mounted upon two separate tracks. The forward rollers38 roll upon the short track sections 39 while the rear wheels 40rollback and forth on the short rear outer track section 41. The objectof this structural arrangement, as aforesaid, is to cause one tray totravel past the other in aback and forth movement. By observing Figure1, it is noted that the Wheels 40 of the tray 30 may travel along thetrack to the rear of the press jaws and come to rest on the rear end ofthe rails 41'which rolls the tray 30 into the pressing plane 12, andsimul taneously therewith the front wheels 38 of the same tray come torest on the rear end of thetrack rail 39, assuming of course the saidtray 30 is moved back into the press when the jaws thereof are open. Asthe tray 39 moves forward out of the press aws, it rolls along theentire length of the rails 37 and comes to rest on the front end thereofunderneath the position originally occupied by the tray 30.

A flexible connection 43-connects the front edges of the trays andpasses around a roller 44 while flexible connection 45 is establishedbetween the rear edges of the two trays and passes around a roller 46.It is observed that themovement of one tray initiates the movement ofthe other thereby causing the two trays to move in unison. The operatorhaving loaded the tray 30, is not required to manually roll it back intothe press jaws for the power means performs that function as will beseen.

Tray operating mechanism .ing the two trays in andio'ut by power, the

same motor means 26 is employed and a connection is established betweenone of the trays and some moving part, of the pressing machine whichautomatically operates the trays as the pressing head closes down to theend that one tray moves in and the other moves out of the pressingmachine during the downward cycle of the head 17.

For the purposes of this description it should he understood that thefulcrum shaft 19 is preferably anchored to the press lever 18 and theshaft 19 therefore oscillates durinc the up and down motion of the head;and this oscillating motion is translated into rectilinear tray'motionby means to be described.

A main operating arm has its upper end an hored to the oscillating shaft19 thel'eby causing}? the lower end thereof to swing back and forthduring the up and down motion of the head. The lower end of the arm 60is fitted with a pin 61 which floats in a slot 62 made in asupplementary arm 63 which has its lower end pivotally mounted on theframe as at 64.. This construction permits the main arm 60 to swi ngtheupper end of the oscillating arm 63 through a large radius by virtue ofthe pivot point 64 being located substantially close to the pin 61. Thetwo arms 60 and 63 are therefore so mounted and arranged as. to afford atravel at the upper end of the arm 63 about equal to the distancetraveled in and out by the trays.

A link 66 has one end thereof pivotally connected to the arm 63 and thefront end thereof is pivotally connected by pin 67 to a slide 68confined in a link guide bar 69. The guide bar 69 is made with a slot 70in which the slide 68 is confined thereby permitting the said slide torun from rear to front without a tray and reverse its movement carryinga tray. The front end of the guide bar 69 is preferably located just alittle lower than the rear end thereof which permits the slide 68 to rundown hill in its outwardly forward movement. The two ends of the guidebar (39 are provided with brackets 71 by which the said guide isanchored to reach bars or bracket frames 11 extending from the rear ofthemachine to the front track extremities thereof to support the severaltracks and the guide in rigid relation upon the frame or legs 15 of thepressing machine.

The main purpose of the slide 68 is to travel outwardly in disconnectedmanner from the conveyor during the rising motion of the head and topick up a conveyor tray at the end of its outer stroke and stand readyto drive the trays on the track, one in and one out, when the head 17moves downwardly toward the buck and to this end the slide 68 is fittedwith a pair of automatically operating hooks adapted to engage their'respective trays 29 or 30 when the slide block reaches its extremeoutward position as will now be described.

In describing the structure and function of the slide 68 reference ismade further to the drawings and particularly the series of views asaforesaid; and in the views Figures 3 to 6 inclusive and Figures 10 and11, the tracks are omitted for clearness in illustration. The slide 68is confined in the slotted guide 69-70 and adapted to reciprocate backand forth therein under the throw of the link 66 for the purpose ofsynchronously moving the trays 29 and 30 in and out of the pressing jawsduring one cycle of the jaw motion. Since the trays are connectedtogether, as by a. flexible cable, it is necessary to pull one tray onlywhich tray thereby causes the other one to travel in the oppositedirection. It is to be noted that the opening cycle of the press jaws,the lifting of the head, is utilized for actuating the conveyor trays,because both cycles. the up and down head motion, would not affordsatisfactory conveyor operation for the reason that excess conveyortravel would ensue; and so it becomes necessary to establish aconnection between the conveyor and press operating mechanism during onecycle of the head operation and to release or disengage said connectionduringthe other cycle of the head movement. In the present The nextoperating cycle comprises the liftdisclosure I have chosen the closingpress moing of the head.

tion as most convenient for illustratingthe principle of automaticallydriving the conslide 68 is in the act of traveling forwardly vey or fromthe press operating means. to the left and such movement is initiatedbyThe slide 68 carries a pair of tray hooks and the thrust of'the linkfitioperating under the each hook, is adapted to individually pick upthrust of the links 60 and 63. \Vhen the slide its respective tray atthe end of the outward 68 st r s to the left, the tray hook 300 readilystroke of the slide and draw the tray back into releases from the pin 78and travel o wardthe press jaws which action of course runs ly incentralized position thereby leaving the the other tray out of thepress. The hook 300 tray in the press. j j is adapted to pick up thetray 30 and carry The lower ray hook i made wi h -11 it into the presswhile the hook 290 is adapt upper Cam face 80 whichpermits it to be deedto pick up the tray 29 and onvey it i t pressed by the pin 78 as thecarriage slide 68 the press. Both of the hooks are pivoted moves rapidlyoutwardly Since the hOOk 290 on pins 75 anchored in the slide-block 68and prings down underneath the pin 78 and 1 each hook is centralized bya spring 76. One ea es the'conveyor tray 30 at rest in the end of thespring 76 is fastened to the swingpress ]3.WS. The hook 290 is also madewith able hook while the other end of the spring is an underneath camface 81 which causes the anchored to the slide block. The tension ofhook to Swing upwardly over the pin 82 anthe springs 76 act tocentralize the hooks in chored to the tray 29 and establish a positive vnormal operating position and each hook is connection with the said traypin 82 as shown permitted to flex up or down, as the case may in Figure10. The action of the underneath I be, for the purpose of executing theseveral cam face 81 is shown as taking place in Fig functions requiredof these tray pick up are 6 by thrusting upwardly on the hook 290 hooks.The upper tray hook 300 is made to establish said connection between theslide with an inclined or cam shaped head 77 the 68 and tray 29. Oncethe hook 290 has purpose of which is to permit the hook to slide snappedinto the position over the pin 82 the past a pin 78 anchored to the tray30. When slide thereafter will haul the tray 29 back slide 68 travelsforwardly sufliciently far into the press and exchange its position foralong the track, the inclined face 77 slides that of the tray 30. Figure10 shows the hook 'past and underneath the pin 78 and the said 290engaging the tray 29 while at rest in presshook 300"snaps intoengagement with the pin ing position and by the time this position is 78as shown in Figure 3 which makes a conreached the press head has closedupon the nection betweenthe conveyor 30'and slide 68; work and tray 29.As the slide again moves and when the slide travels rearwardly toforwardly, the hook 290 moves away from wards the jaws the tray 30 iscaused to trathe tray 29 for the hook 290 parts from the verse the trackand quickly move into the '.tray 29 leaving said tray in position withinpressing plane 12 thereby causing the trays to the press jaws. Theoifset position of the exchange positions. As the slide 68 starts hookhead permits it to move away from the traveling to-the right from theposition in tray pin 82 when the slide 68 moves forward Figure. 3 andapproaches the position in away from the tray 29 to leave it in thepress. Figure 4 the-spring 7 6 permits the hook 300 Preferably the link66 which forms part. of to work upwardly compensating for the up theoperating mechanism is capable of slight hill travel of the tray 30, forit is to be apprerelative extensionand for this purpose inciated thatthe said upper tray 30 must travel p ates the Spring plunger 84 whichfor 7 high above the outcoming tray 29 in order all Practical P pP05595595 a p t-3 that the trays pass one over the other going inopposite directions, and so I have designed the oscillating tray hook300 having capacity to maintain fixed connection with the tray 30 but atthe same time swing on its pivot 75 to compensate for the somewhatirregular travel of the tray 30. As the tray 30 approaches the pressjaws it must necessarily run down hill on its track in order that itreach the common pressing plane 12 and here again the spring 76exercises a centralizing effort on the said tray hook 300 to straightenit out as ficiently strong to pull first one tray and then the othertray into the press jaws without compressing to any appreciable extent.Since the trays roll very easily over the track, there exists nocompression of the spring 84 until the head 17 closes down upon the workbut at this stage of the operation itis appreciated how the tray muststop still in the jaws at the instant of the imposition of final ressureby the motor. In other words the ead 17 clamps down on the work on thetray which By reference to Figure 5it is noted that the vIll!) stops thetray movement, and since the imposition of final heavy pressure on thework shown in the position of Figure 5. By the may causeslightadditional or excess travel time the tray 30 reaches the pressingposition of the arm 63 after the tray has ceased. to inside the aws, thehead 17 has closed down travel, it follows that lost motion or relativeupon the work and the other tray 29 has motion must occur between thestationary. reached the outer position shown in Figure 5. tray andslightly moving press mechanism.

move the link 66 after the tray has in fact stopped still, and thespring plunger 84 permits this compensation to ensue without damage tothe machinery.

C'omplete and joint operation Assuming that one tray is in the pressundergoing pressure, the operator then has time to unload and reload theoutstanding tray. He swings the handle 28 to cause a forward movement ofthe connecting rod 20 which lifts the head off of the work and rapidlymoves the slide 68 forwardly causing it to pick up the outer tray; andthe motor drive mechanism continues until the wheel or crank 21 makes acomplete revolution which performs the double function ofsimultanenously exchanging tray positions and closing the head down. Themotor or its clutching mechanism is timed to automatically stop afterthe press head has completed both cycles of operation whereby it risesand falls in relation to the buck in rapid motion and dwells underpressure in position of Figure 1 until the operator again swings thehandle 28 to repeat the operation.

N 0 time is lost in pressing on the machine for one observes that Ipreferabl employ motor means adapted to continuous y execute the openingand closing press head move ment once the operator actuates the controlhandle 28. In other words both the opening and closing cycle followsrapidly one after the other which is unlike old pressing machines now inuse because in the old machines the head must remain up until the workis removed from the buck and new work placed thereon but not so in mymachine for I have so designed the head lifting mechanism that it risesa very short distance off the buck and instantly goes back down for bythis time the tray with new 'work has automatically moved into place forpressing treatment.
